In this article we develop a nonparametric estimator for the local average response of a censored dependent variable to endogenous regressors in a nonseparable model where the unobservable error term is not restricted to be scalar and where the nonseparable function need not be monotone in the unobservables. We formalize the identification argument put forward in Altonji, Ichimura, and Otsu (2012 Altonji, J. G., Ichimura, H., Otsu, T. (2012). Estimating derivatives in nonseparable models with limited dependent variables. Econometrica 80:17011719.[Crossref], [Web of Science ®] [Google Scholar]), construct a nonparametric estimator, characterize its asymptotic property, and conduct a Monte Carlo investigation to study its small sample properties. Identification is constructive and is achieved through a control function approach. We show that the estimator is consistent and asymptotically normally distributed. The Monte Carlo results are encouraging.  相似文献

This study uses content analysis to provide a qualitative exploration of how life roles are affected by frequent (i.e. at least weekly) gambling, based on in-depth interviews with a community sample of 161 non-treatment-seeking frequent gamblers. Over half (51.6%) of the participants indicated problems associated with gambling and 131 examples were identified. The majority of problems were relational (50.4%), followed by financial (19.8%), work (13.7%), and school related (8.4%). Slightly less than half of participants (41.7%) reported losses due to gambling and 92 examples were provided. The most frequently reported loss was identity related (54.3%), which included self-esteem/shame (38.0%), estrangement from family (34.0%), estrangement from friends (16.0%), and estrangement from work colleagues (6.0%). Additional losses included health (29.3%) and financial (8.7%). Almost two-thirds of participants (64.6%) reported difficulty concentrating in family (18.4%), work (16.8%), and school (9.6%) activities, whereas general concentration problems comprised an additional 48.8% of the examples provided. Half of participants (49.1%) discussed behavioral withdrawal due to gambling, which included withdrawal from work (44.3%), relationships (24.5%), school (15.1%), and personal (6.6%) activities. These findings paint a complex picture of how gambling interferes with different life roles for some frequent gamblers, identifying important areas for future research and practice.  相似文献

In this paper, we argue that complex forms of selfhood emerge in relation to rapid economic and social changes unfolding in the early stages of the twenty-first century. We draw on literature that explores youth at risk, entrepreneurial selfhood and neoliberalism to argue that young people are developing modes of transition that allow them to acclimatise to economic and social insecurity. It is an insecurity borne of a paradoxical reliance on, and failure of, neoliberal forms of economics and society. In the context of a post-Global Financial Crisis (post-GFC) world, we explore how young people take responsibility for their uncertain futures. Via our critique of how young people are supposed to manage their lives from education to employment, we argue that a form of selfhood emerges as they are challenged by limited education and employment opportunities. We call this selfhood the guerrilla self. We use this term to designate types of identity that require participation through resistance, institutionalisation through the appearance of not being institutionalised, and individualism in the midst of a failure of individualism. In making this case, we draw on stories told by young people in the USA planning for a future in a post-GFC world.  相似文献

Cities evolution tree and applications to predicting urban growth   总被引:4,自引:0,他引:4  
China’s unprecedented urbanization and economic modernization have brought about significant growth and land use changes in cities and their surroundings. Traditional analyses of the relationship between urbanization and land use change have not fully incorporated important factors like city function or developmental stage. We define and apply a new visualization and analysis tool—an evolution tree—showing how an understanding of evolutionary pathways taken by growing cities contributes to visualization and forecasting of urban development and spatial expansion. We clustered 253 Chinese cities by type and developmental stage, arranging them in a “tree” structure, with types grouped as branches and leaf position along branches reflecting developmental stage. Urban growth rates are higher for business-oriented, manufacturing-oriented, and functionally comprehensive cities than for those oriented toward tourism. Extent of spatial growth is dominated by city type and developmental stage. Cities evolve along typical pathways, punctuated by occasional leap developments across functional types.  相似文献

Heterosexual people with more positive attitudes to lesbians and gay men generally believe that homosexuality is immutable, is not a discrete social category, and that homosexuality exists in all cultures and time periods. Equivalent beliefs about heterosexuality and beliefs about components of sexuality have been less often researched. 136 people with diverse sexualities described heterosexuality as more universal across history and culture than homosexuality (Study 1). 69 heterosexual-identified participants similarly believed that love, identity, behavior, and desire were more historically invariant aspects of heterosexuality than of homosexuality (Study 2). Less prejudiced participants thought all components of homosexuality—except for identity—were more historically invariant. Teasing apart beliefs about the history of components of heterosexuality and homosexuality suggests that there is no “essential” relationship between sexual prejudice and the tension between essentialist and constructivist views about the history of sexual identity.  相似文献

George Lawson and Barry Buzan's The Global Transformation advances the claim that International Relations (IR) has mistakenly overlooked the Long Nineteenth Century as a transformative era. They argue this period saw a shift in the mode of power, i.e. how power was utilised and expressed, and not merely a change in how it was distributed amongst competing political entities. The following offers a sympathetic critique of their theoretical claims. Highlighting the role of geopolitics and the societal changes of the public sphere, the article argues that the historical sociological method utilised by these authors is ‘neither realist nor liberal enough’.  相似文献

We propose a shift in emphasis when communicating to people when the objective is to motivate household disaster preparedness actions. This shift is to emphasize the communication of preparedness actions (what to do about risk) rather than risk itself. We have called this perspective “communicating actionable risk,” and it is grounded in diffusion of innovations and communication theories. A representative sample of households in the nation was analyzed using a path analytic framework. Preparedness information variables (including content, density, and observation), preparedness mediating variables (knowledge, perceived effectiveness, and milling), and preparedness actions taken were modeled. Clear results emerged that provide a strong basis for communicating actionable risk, and for the conclusion both that information observed (seeing preparedness actions that other have taken) and information received (receiving recommendations about what preparedness actions to take) play key, although different, roles in motivating preparedness actions among the people in our nation.  相似文献
